My wife's old laptop was excruciatingly slow. No amount of basic maintenance would work. That's when I called Paul at XPC. He's done work for me in the past on a high-end machine that I use for studio work, and did an excellent job. I brought the laptop to him and we decided on replacing the old hard drive with a new SSD.
The work involved making a backup of the stuff on the old hard drive, replacing the hard drive with the new SSD, installing the backup, and setting everything up so it worked perfectly when my wife turned it on. She was amazed how fast everything was after the upgrade. Thanks Paul.
